From 5122dfae5d3cd68e0b6e5e08597df91ba79770aa Mon Sep 17 00:00:00 2001 From: Shengzhou Liu Date: Fri, 25 Apr 2014 16:31:22 +0800 Subject: powerpc/85xx: add T4080 SoC support The T4080 SoC is a low-power version of the T4160. T4080 combines 4 dual-threaded Power Architecture e6500 cores with single cluster and two memory complexes.

These helpers need to have awareness of already occupied TLB entries. We already had them in sync in non-relocated mode, but need to resync them when we move into relocated.

It has not been used for powerpc, until recently changing to use generic board architecture. The boot flag is added as a return value from cpu_init_f().
